What is the maximum recommended daily amount of full fat milk for a 12 year old boy, assuming an average weight for 12 year olds at 40kg (88lb). Is 1.5 english pints per day too much?

    What do you mean what would happen? It's just milk.

    @LeoCornelius you can and should edit your question, if you want to add new information or clarify the given ones. If you give important content in a comment, it might get lost in the future or people just don't read it.

    @Jan Currently the Q is a bit on the low quality side, broad & vague, lacking prior research, etc. You yourself had to ask for clarification. The box underneath explains that with an edit this might be salvaged. Who does the edit is unimportant, that an edit improves the Q is. Apr 27, 2018 at 10:59

    @LeoCornelius I voted to re-open – despite the Q still being in need of further improvement. Can you balance your research for the answer as to splice something of your research effort into the question? (Your assumptions about "acidity" might fit?) Apr 27, 2018 at 12:59

I have found no credible source that would mention "maximum recommended daily amount of full fat milk."


The US Department of Agriculture recommends the following daily amounts of dairy for children and teens:

  • Two through 3 years old: 2 cups (480 milliliters)
  • Four through 8 years old: 2½ cups (600 milliliters)
  • Nine through 18 years old: 3 cups (720 milliliters)

A 12 year old boy drinking 1.5 US pints (710 milliliters) of milk fits in.

Regarding the concern that milk can make blood acidic: The acidogenic effect of foods can be estimated by "renal acid load" (the amount of acids secreted through the kidneys). According to this article (Table 2), renal acid load after one serving (240 mL) of full fat milk is 3.6, and after low-fat milk 3.9, which means it is not fat in the milk that contributes to the acidity. Renal acid loads of certain other foods are much higher: one serving of cheese (17-57), meat (14-21), fish (10-32), nuts (16-36).

According to one 2015 systematic review, milk consumption does not seem to contribute to kidney stones.

There is an ongoing debate if milk is healthy or unhealthy and there are opinions that milk is only for children (or even only for small children). Most of research shows that milk consumption as such is not bad for health (PubMed Central). On the other hand, plant-based diets may be healthy enough, even for children (PubMed Central).

    You need to make it clear that the 1.5 pints you mentioned for 12 year olds is 1.5 US Pints as that is 1.25 UK Pints because we use the imperial pint measure May 9, 2018 at 14:55
